Histology scoring of DSS model.

Inflammation	Area of infiltration	Crypt damage	Edema
0= none	0= none	0= none	0= none
1= mild	1= mucosa	1= basal 1/3 damaged	1= ≤2x submucosal thickness
2= moderate	2= mucosa & submucosa	2= basal 2/3 damaged	2= ≥2x submucosal thickness
3= severe	3= transmural	3= only surface epithelium intact
		4= entire crypt and epithelium lost
